comment Theoretically, what technique would one use to modify a virus so that it only affected a subset of the population?
Also - there would be a strong selection for mutant viruses which gained the ability to recognise the receptor variant in the immune population.

comment How does the Cuttlefish camouflage itself accurately despite being color-blind?
@terdon I'm suggesting that there is no need to see the colours. If other (strictly non-visual) sensory inputs are an indicator of lying on a sandy surface then these could be used to promote the "correct" choice of colours.

comment How does the Cuttlefish camouflage itself accurately despite being color-blind?
Plants have evolved coloured flowers which they cannot see. Insect mimics have evolved patterns of colour which they cannot see. If the phenotype offers an advantage it can be selected for. Presumably cuttlefish can use other sensory cues to determine the nature of their surroundings and this information can be used as an input into the chromatophores and iridophores.

comment Essential amino acid codons
Perhaps worth adding that since most (all?) human initiation codons are AUG, most (all?) proteins contain an essential amino acid right there.
